The most intuitive and natural approach for building garments takes its inspiration from the traditional garment industry where garments are created from two-dimensional patterns and then seamed together. MIRACloth uses this approach. Working with 2D patterns is the simplest way of keeping an accurate, precise and measurable description and representation for a cloth surface. In the traditional garment and fashion design approach, garments are usually described as a collection of cloth surfaces, tailored in fabric material, along with the description of how these patterns should be seamed together to obtain the final garment. Our virtual garment design system reproduces this approach by providing a framework for accurately designing the patterns with the information necessary for their correct seaming and assembly. Subsequently, these are placed on the 3D virtual bodies and animated along with the virtual actor's motion. In the following sections, we describe the different components — mechanical model, numerical resolution, collision detection and collision response — to develop for the simulation of clothes, then, we provide the different steps and tasks involved in dressing virtual actors, constructing and animating garments on them.

Optimized Model

It is an innovative design method in physics that product layout design is abstracted into convex hull plus rubber band simulation layout mode by setting up the optimized model. Based on the physics model of Newtons Second Law, this paper analyzed collision detection methods during the process of realizing reasonable layout, and it is founded that real-time collision detection and collision response during movement, produced components within the given beat, appeared to be the key content of resolving digital model design. In this paper, Area Difference method was adopted to detect when the collision occurred during component movement and what kind of state the component tended to be in collision. At the same time, it also determined the interference degree, solved critical point pose for collision response as well as its generation time and related torque and force, which can confirm the components continued movement model of rotation and sliding. Meanwhile, it employed the Judgment Matrix method to analyze collision response so as to confirm the collision interference relationship and collision action state, movement possessing mode (rotation, sliding and retraction, etc.) within the remaining time after collision with given beat during the layout process. All these provided with a practical solution for digital design of optimized model based on convex hull plus rubber band simulation compact layout.

Abstract In this paper computer implementation of automated simulation of rigid bodies in collision is presented. It can be used for automatic simulation of unconstrained and/or constrained mechanical systems. The key tasks include feature extraction, collision detection, constraint identification, collision response, and simulation. Feature extraction includes volumetric feature extraction such as mass, volume, density and moment of inertia, and planar geometric feature extraction like the faces, edges, vertices and their inter-relationships. Collision detection is a kinematic problem involving the positional relationships of rigid bodies in space, while collision response is a dynamic problem involving the prediction of rigid body behavior according to physical laws. Case studies are used to explain the behavior of a typical system comprising of two rigid bodies to explain the underlying principles.

Purpose – The 3D dynamic clothing simulation is widely used in computer-added garment design. Collision detection and response are the essential component and also the efficiency bottleneck in the simulation. The purpose of this paper is to propose a high efficient collision detection algorithm for 3D clothing-human dynamic simulation to achieve both real-time and virtually real simulation effects. Design/methodology/approach – The authors approach utilizes the offline data learning results to simplify the online collision detection complexity. The approach includes two stages. In the off-line stage, model triangles with most similar deformations are first, partitioned into several near-rigid-clusters. Clusters from the clothing model and the human model are matched as pairs according to the fact that they hold the potential to intersect. For each cluster, a hierarchical bounding box tree is then constructed. In the on-line stage, collision detection is checked and treated parallelly inside each cluster pairs. A multiple task allocation strategy is proposed in parallel computation to ensure efficiency. Findings – Reasonably partitioning the 3D clothing and human model surfaces into several clusters and implementing collision detection on these cluster pairs can efficiently reduce the model primitive amounts that need be detected, consequently both improving the detection efficiency and remaining the simulation virtual effect. Originality/value – The current methods only utilize the dynamic clothing-human status; the authors algorithm furthermore combines the intrinsic correspondence relationship between clothing and human clusters to efficiently shrink the detection query scope to accelerate the detection speed. Moreover, partitioning the model into several independent clusters as detection units is much more profitable for parallel computation than current methods those treat the model entirety as the unit.

Purpose To improve the apparel e-customized system and meet consumers’ personalized requirement in the e-customization, the purpose of this paper is to develop an e-customized co-design system on garment design (ECS-GD) that enables users to co-design garment and communicate with stakeholders. Design/methodology/approach The e-customized co-design system mainly consists of function and modular structure, communication and evaluation modular. Based on the evolutionary algorithm and fuzzy theory, the e-customized system model is proposed with a presentation of garment interface. Based on the parameters of skirts, technical sketches, fabrics, color, patterns, comments and scores, the decision is made by consumers. Findings For the system to be effective, the system was conducted by multi-individuals co-work (consumers, designers, manufacturers and experts). The data flow was congruent to the design knowledge. The expert evaluation and communication were involved in the proposed system. Research limitations/implications The limitation of this study is that the system is not tested in experiments. The model, main function and data flow are proposed in this study, which is important in the e-customized co-design system development. Originality/value Compared to the e-shopping and garment recommendation, the proposed ECS-GD is a good approach to improve the existing e-customized system and a well solution to help consumers with design knowledge recommending, professional suggestions and evaluations. Besides, the sketches and knowledge recommendation are provided to consumers which is a learning process.

Scoliosis is one of the most frequently occurring morphological problems in people. People with such an abnormal curve of the spine face a huge problem, not only from the medical point of view but also from that of garment design and production processes. The current paper brings a novel designing technique to develop an adaptive 3D model of the complicated anatomical shape of the human vertebrae using 3D digitization technologies. Even though it is not as accurate as scanning approaches, it is accurate enough for several applications, including visualization and constructing statistical shape models. Thus, the adaptive model will further integrate with the full skeleton and then to the body shapes of scoliosis patients, not only for an easy garment design process but also to produce comfortable and high-performance garments. The model has also the benefit of adjusting for each tissue to all kinds of spine parameters, such as the height and the angles of the bones and disks (especially the three characteristic planes: sagittal, coronal, and transverse). Thus, the full adaptive skeleton model and later its garment design system, considering the current adaptive vertebrae model for fitted, comfortable and well-performing scoliosis patients garment products, could be developed.
